Membrane type liquid desiccant air conditioner

Abstract

The invention discloses a membrane type liquid desiccant air conditioner. The membrane type liquid desiccant air conditioner comprises a compressor, an auxiliary gas cooler, a first heat exchanger, a second heat exchanger, a liquid storage tank, a hollow fiber membrane type regenerator, an auxiliary cooler and a hollow fiber membrane type desiccant device. The liquid desiccant air conditioner is driven by a carbon dioxide circulating heat pump, carbon dioxide is used as a refrigerating working medium, is environmentally friendly and free of pollution and has obvious advantages over traditional refrigerants such as R134a, R22 and R407c causing environment destruction, and the carbon dioxide working medium has small influences on the environment. Meanwhile, carbon dioxide transcritical cycle is high in heat release temperature, and the desiccant liquid regeneration demand can be well met. In addition, the hollow fiber membrane type regenerator and the hollow fiber membrane type desiccant device are used as liquid desiccantion and regenerating parts, and thus the problem that fed air carries desiccant liquid due to the fact that liquid desiccant of a traditional liquid desiccant air conditioner makes contact with the air is solved.

Description

technical field [0001] The invention relates to the technical field of refrigeration and dehumidification, and more specifically relates to a membrane solution dehumidification air conditioner. Background technique [0002] In the prior art, the independent temperature and humidity control air-conditioning system separates the temperature and humidity control into two independent system controls, which avoids the waste of energy quality caused by the traditional condensing air-conditioning system using the same low-temperature cold source for dehumidification and cooling and high energy consumption. As a humidity control system, the solution dehumidification air conditioner bears all the latent heat load and part of the sensible heat load in the room. Due to the fluidity of the dehumidification solution, the solution dehumidification air conditioner can cool the dehumidification solution well to meet the dehumidification requirements. Heating meets regeneration needs. Beca...

Problems solved by technology

[0006] In view of this, the purpose of the present invention is to provide a membrane solution dehumidification air conditioner, the structural design of the membrane solution dehumidification air conditioner can effectively solve the cooling capacity and heat provided by the solution dehumidification air conditioning system driven by the heat pump in the prior art. The cold energy required for dehumidification does not match the heat required for regeneration and has a great impact on the environment
